I assembled my tiny arcade. I downloaded the games zip file, unzipped it and put it on the SD card I bought. the system sees the games and they appear on the menu. But when I go to load a game it runs a red line followed by a green line across the screen. Then it freezes.  The games that came preloaded on the system ran fine when I first tested it.

I tried to update the menu from the Arduino program. The program does not find the game port for the system. I have a Ardoboy and I used the same game cable that works with it but it will not load the files. I tried to reset the board but it just turns on when the button closest to the USB port is held down like normal. Any advice?
